Blockchain is a digital ledger that records transactions across distributed computing systems, making it difficult to change, hack, or fraudulently alter the data. The document discusses how blockchain can be applied in various energy applications, including solar/battery systems, electric vehicle infrastructure, and transmission/distribution systems. It also describes how smart contracts specific to the energy sector can be legally binding. The BEC methodology for blockchain design and implementation is presented, focusing on business process mapping. Finally, a GridMix smart energy contract reference model is introduced as the first use case to be implemented using Ethereum.
